OE Engine or not???

[Steve V.]

1960 VIN 105821 which should be April 2 or so. 519 engine block with a C90 date. Should be March 9, right? Intake is C120, March 12. Head is C110, March 11. So far so good.

Pad stamp is F0314CQ which should be base 230 HP build date March 14th. No VIN derivative on pad.

I find different reports on when the VIN derivative was supposed to have started. What's the real answer? Also the 1 the pad stamp is not the letter I but simply an I.

I am not sure what the broach marks should look like, but examining the pad I do not see what has been described as swirl marks from having the block decked.


What's the verdict, original or not?

Doesn't look like factory broach marks on the pad.

I don't know. That's what I am trying to find out. What about the vin #. When did they start putting it on the pad?

Yeah, looks like someone took a light abrasive left to right on the pad---

My ancient Judging Guide says VIN sramp appeared in Dec '59 or Jan'60, so a March engine should be Vin Numbered if original, as well as the issues with the machining marks on the pad.

Yes, the broach marks are NTFP (left and right, S/B up and down) IMO. IIRC, the VIN was stamped on the engine pad starting around mid-December 1959, and IIRC the earliest I have heard of was about #1617. But I am no expert on '60s so please correct my recollections from a while back, if necessary.

If you look carefully there appears to be the remnants of broach marks near the head.

#1617 is the first one I've seen with a VIN stamping, done free-hand and #5874 is the last one I've seen done free-hand. The OP's VIN should be stamped free-hand as well however, the "O & C" in the assembly stamp are different than any of the 1960 pad pictures I've collected over the years. I'd say it's NOT the original engine.

The surfacing on the deck is 90 degrees off and there is still the lifted edges of the numbers from stamping process which is deep. So I think the incorrect surfacing was done before application of stamped numbers.

Mine was just 10 cars later, but not hand stamped.
